Labmaster Universal - Model 175-Image

With instrument uncertainty to 2 millionths of an inch (50 nanometers), the Labmaster Universal - Model 175 is suitable for virtually all Internal (ID) and external (OD) measuring applications. This laser-based universal length measuring system (ULM) has been developed by Pratt & Whitney for gage calibration laboratories that need to precisely measure length, outside diameter, inside diameter, pitch diameter, lead, major/minor diameter, taper, linear displacement, and thickness.

High accuracy is maintained by its laser interferometer, zero Abbe offset design, and large measuring table with center position, height, pitch, and yaw controls. The computer-controlled precision air bearing slide and gaging fingers remove operator-influenced errors commonly observed with traditional gaging methods by maintaining constant force. It also greatly minimizes wear and tear to both the measuring standards and the instrument.

The ULM is capable of measuring gage blocks, end standards, plain rings, threaded rings & plugs, API gages, pin & plug gages, tapered plugs, cylindrical setting gauges, micrometers, indicators, LVDTs, calipers, and snap gauges with instrument uncertainty to 2 millionths of an inch (0.05 micron). It is suitable for virtually all ID and OD applications through its wide 0.020-inch (0.5 mm) to 14-inches (356 mm) measuring range. The ULM includes Pratt & Whitney's GageCal software that automatically enters tolerances for rings, plugs, pins, balls, threads (calculates pitch/major diameter) and flags out of tolerance conditions.

The Labmaster Universal - Model 175 is also a popular measuring instrument in the bearing industry. The five basic types of anti-friction bearings can easily be measured on the ULM. They include: tapered bearings, needle bearings, ball bearings, spherical bearings, and cylindrical bearings. Measuring characteristics include: internal diameter, external diameter, outer raceway diameter, inner raceway diameter, radial internal play (radial internal clearance) and axial internal play (axial internal clearance).

Other specialty measuring applications include: gears, shafts, optics, film thickness, automotive parts, aerospace parts including aircraft engine parts, and your precision components can all be measured on the ULM.
